Update database references from water_meters to consumers

[Copilot]

The application was referencing a water_meters table with water_meter_id foreign keys, but the actual database schema uses a consumers table with consumer_id foreign keys. The consumers table also lacks an is_active field that was being checked.

Changes

database.py

• water_meter_exists() → consumer_exists(), removed is_active check
• insert_image() now uses consumer_id parameter
• get_water_meter_info() → get_consumer_info(), queries consumers directly

main.py

• Form parameter: waterMeterId → consumerId
• Updated filename generation and error messages

init.sql

• Removed water_meters and readings tables
• images.water_meter_id → images.consumer_id foreign key
• Simplified consumers table structure

README.md

• Updated API documentation and examples

Example

# Before
if not db.water_meter_exists(waterMeterId):
    raise HTTPException(404, f"Water meter with ID {waterMeterId} not found or inactive")

# After
if not db.consumer_exists(consumerId):
    raise HTTPException(404, f"Consumer with ID {consumerId} not found")

-- Before
INSERT INTO images (water_meter_id, image_url, processed, created_at)

-- After
INSERT INTO images (consumer_id, image_url, processed, created_at)

Original prompt

Problem

The application currently references water_meters table and waterMeterId parameters, but the actual database uses consumers table with consumer_id foreign key.

Database Schema

The actual database structure is:

Table: consumers

• id (INT, PRIMARY KEY, AUTO_INCREMENT)
• name (VARCHAR(255), NOT NULL)
• address (VARCHAR(255))
• created_at (TIMESTAMP)

Table: images

• id (INT, PRIMARY KEY, AUTO_INCREMENT)
• consumer_id (INT, NOT NULL, FOREIGN KEY → consumers.id)
• image_url (VARCHAR(255), NOT NULL)
• processed (TINYINT(1), DEFAULT 0)
• created_at (TIMESTAMP)

Required Changes

1. Update database.py

• Change all references from water_meters to consumers
• Change all references from water_meter_id to consumer_id
• Update method name from water_meter_exists() to consumer_exists()
• Update SQL queries to use correct table and column names
• Remove is_active check since consumers table doesn't have this field

2. Update main.py

• Change parameter from waterMeterId to consumerId
• Update method calls from water_meter_exists() to consumer_exists()
• Update all variable names from water_meter_id to consumer_id
• Update filename generation to use consumer_id
• Update error messages and documentation to reference "consumer" instead of "water meter"
• Update endpoint documentation

3. Important Notes

• The consumers table does NOT have an is_active field, so remove any active status checks
• The images table uses consumer_id as foreign key, not water_meter_id
• All functionality should remain the same, just with correct table/column references

Testing

After changes, the /upload endpoint should:

1. Accept consumerId parameter (integer)
2. Validate that consumer exists in consumers table
3. Upload image and store path in images table with consumer_id reference
4. Return success response with image details

Projekat je završen! ✅

Uspešno sam ažurirao sve reference sa water_meters na consumers tabelu:

Šta je urađeno:

• ✅ database.py - metode prebačene na consumer_id i consumers tabelu
• ✅ main.py - parametar promenjen sa waterMeterId na consumerId
• ✅ init.sql - uklonjena water_meters tabela, images tabela koristi consumer_id
• ✅ README.md - dokumentacija ažurirana

Testovi:

• ✅ Svi testovi prolaze
• ✅ Nema sigurnosnih propusta (CodeQL sken)
• ✅ Code review završen
• ✅ Nema više referenci na water_meters
